Pressure Release Valve Solenoid: Testing and Inspection

1. With ignition switch OFF, disconnect coupler from valve.





2. Check resistance between two terminals of tank pressure control solenoid vacuum valve.

Resistance: 28 - 36 ohms at 2O°C (68°F)

If resistance is as specified, proceed to next operation. If not, replace.
3. Disconnect vacuum hoses from tank pressure control solenoid vacuum valve.





4. Blow into nozzle "A". Air should come out of filter and not out of nozzle "B".





5. Connect 12V-battery to solenoid vacuum valve terminals. In this state, blown nozzle "A". Air should come out of nozzle "B" and not out of filter. If check result is not as described above, replace solenoid vacuum valve.
6. Connect solenoid vacuum valve coupler securely.
7. Connect vacuum hoses securely.
